Magnitude 7.7 Earthquake Kills Over 200 in Pakistan
September 25, 2013 | The Weather Channel
At least 200 people were killed by a magnitude 7.7 earthquake in Pakistan’s Baluchistan province.
There is a report that a mud volcano formed an island off the coast in the Arabian Sea at the same time that the earthquake was occurring. The Weather Channel video has comments on this from a USGS scientist.
The Largest Deep Earthquake Ever Recorded|
September 22, 2013 | University of California Santa Cruz
“A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers (378 miles), the intense pressure on the fault should inhibit the kind of rupture that took place.” Quoted from the University of California Santa Cruz press release.
Monitoring Slow Earthquakes to Predict Large Earthquakes?|
September 16, 2013 | Penn State University
“We currently don’t have any way to remotely monitor when land faults are about to move” [...] “This has the potential to change the game for earthquake monitoring and prediction, because if it is right and you can make the right predictions, it could be big.”
Explosive Magma Can Lurk for 100000 Years|
September 12, 2013 | University of Washington
“Reservoirs of silica-rich magma — the kind that causes the most explosive volcanic eruptions — can persist in the Earth’s upper crust for hundreds of thousands of years without triggering an eruption, according to new University of Washington research.”
Detecting Large Landslides in Remote Areas|
September 4, 2013 | NASA Earth Observatory
“Even when they occur in remote areas, large landslides can dam rivers and lead to devastating downstream floods. [...]
Automated earthquake detection systems are tuned to monitor intense, “short-period” waves produced by sudden slips along tectonic faults. Landslides produce seismic waves as well, though their short-period signal is weak. Instead, they make powerful long-period waves that are sometimes detectable at great distances.” Quoted from the Earth Observatory article.
2011 Tohoku Earthquake and Seiches in Norwegian Fjords|
August 26, 2013 | LiveScience
The March 11, 2011 Magnitude 9.0 earthquake that shook northeastern Japan also produced seiches in Norweigian fjords.

Imploding a Building to Learn about the Hayward Fault
August 15, 2013 | USGS
“When 13-story Warren Hall is imploded by demolition experts this weekend on the Hayward campus of California State University, East Bay, U.S. Geological Survey scientists will monitor the pulse of energy on nearly 600 seismometers temporarily placed in a two-mile radius around the building with help from hundreds of citizen-scientist hosts and volunteers.” Quoted from the USGS website.

USGS on Man-Made Earthquakes|
July 22, 2013 | USGS
“The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. [...] This increase in earthquakes prompts two important questions: Are they natural, or man-made?” Quoted from the USGS blog post.
July 21, 2013 | MIT
“But there remains one lingering mystery: If the Earth arose from the collision of asteroids, its composition should resemble that of meteoroids, the small particles that break off from asteroids. But to date, scientists have found that, quite literally, something doesn’t add up: Namely, the Earth’s mantle — the layer between the planet’s crust and core — is missing an amount of lead found in meteorites whose composition has been analyzed following impact with the Earth.” Quoted from the MIT press release.

Did the Lower Crust Flow on Mars?|
July 19, 2013 | Speaking of Geoscience Blog
“In particular, the southeast region of Tharsis bears strong resemblance in structure and topography to eastern Tibet. High topography and thick crust of eastern Tibet produces long, low-gradient plateau margins that may be caused by the flow of weakened lower crust. This has me thinking: if the lower crust flows in Tibet, did it do so on Mars?” Quoted from the Speaking of Geoscience article.
